VPIM Networking

Overview: VPIM Networking

Cisco Unity supports the Voice Profile for Internet Mail (VPIM) protocol, which is an industry standard that allows different voice messaging systems to exchange voice, fax, and text messages over the Internet or any TCP/IP network. VPIM is based on the Simple Mail Transfer Protocol (SMTP) and the Multi-Purpose Internet Mail Extension (MIME) protocol.

For information about the VPIM-compliant voice messaging systems that Cisco Unity supports, see Supported Hardware and Software, and Support Policies for Cisco Unity, at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_installation_guides_list.html. Note that VPIM Networking can be used for messaging between Cisco Unity servers that are in different directories, including messaging between Cisco Unity with Microsoft Exchange and Cisco Unity with IBM Lotus Domino systems.

VPIM Networking is a licensed feature. If your organization has multiple Cisco Unity servers networked together using Cisco Unity Digital Networking (and, therefore, accessing subscriber data in the same directory), only one server in the Digital Network needs to be licensed and configured for VPIM Networking. The Cisco Unity server configured for VPIM Networking is referred to as the bridgehead server. For more information on obtaining licenses for Cisco Unity features, see the applicable Licensing for Cisco Unity white paper, at http://www.cisco.com/en/US/products/sw/voicesw/ps2237/prod_white_papers_list.html.

To use VPIM Networking, you must choose the applicable options when you run the Cisco Unity Permissions wizard. For detailed information, see Permissions wizard Help, which is available in Tools Depot on the Cisco Unity server.
